T all whom t may concern:

Be it known that I, GILBERT F. QUINN, a citize the United States of America, residg at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in a Combined Refrigerator and Freezer; and I do hereby declarev the following to be a full, clear, and exact description of the invention, such as will -zo enableother skilled in the art to-which it api ake and use the same. vention relates to improvements in a ined refrigerator and freezer, and more particularly to certain principles of construcf5 tion which tend to increase the refrigerating and freezing power and to regulate the degree of temperature.

with suitable air spaces and non-conducting 2o walls and arranged and constructed intethe refrigeratingfor freezing room is a partition formed by a series of angular sections arranged one above the other and forming 2 5 between each two sections an open space lead-A ing from the refrigerating or freezing room extending above the lowest point of the section immediately above it, thus forming be- 3o tween each two sections an inverted V` shaped open space, the object of which will be hereinafter more fully set forth. Between the bottom of the ice bunker and the bottom of porting bars placed at short distances apart, and extending from the lower section of said partition over said ice bars, and thence to the wall of the ice bunker is a wire netting to hold small particles of ice and salt. Under- 4o .neath the ic`e bunker are an inclined drip pan and a trap leadingdown through the refrigerating case, and a partition which prevents the water from passing through into the refrigeratinglor freezing room. At the top of the refrigerating room is a ceiling inclined downwardly away from the ice bunker. The walls of the ice bunker have a shield with inclined openings therein leading to a cold air v space betwieen the partition and refrigerator 5o case. .l

The object and operation of these several It consists in a containing case constructed riorly as follows: Between the ice bunker and,

into the ice bunker, the apex of each sectionv the refrigerator case is a series of ice sup-V' parts, together with certain other details of construction, will be hereinafter more fully described. f

In the. drawings herewith accompanying and making a part of this application, Figure 1 is a vertical longitudinal section. Fig. 2 is a horizontal section of the same.

Sameletters refer to like parts.

In said drawings a represents the case 6o proper of my improved refrigerator and freezer. This case may be made in any convenient or desirable way. As at present constructed, it rests upon the floor and has an outside wall b, dead air space c, interior wall d, insulator e, air space f, and inner wall g.

It also has suitable doors leading into the refrigerating roornand into ,thel ice bunker.

.'Thespace formed by the interior wall g is divided into two parts by a partition formed 7o of a series of sections h arranged to form an angle and placed one above the other leaving a space j between each two sections. These sections have their ends supported in any convenient manner against the walls of the case. These sections are so arranged thatthe yapex of one is higher than the lower extremity of the one next above it, so that said spaces j between each two adjacent sections form as it were air siphons leading from the 8o refrigerating room lo into the ice bunker Z.

To reduce -the temperature in the refrigerating room below the point of freezing, it will be necessary to break up in some measure the ice in the ice bunker and mix therewith a quantity of salt to promote rapid melting of the ice. In order to do this, it is`necessary to provide means or openings for the inser tion of an ice breaking tool into thedmnk'e-r at levels below the door m. To accomplish 9o this object, I leave out half of each alternate section c next to the refrigerating room.

At the bottom of the ice bunker is a series of bars n resting upon suitable supporting bars o. Extending from the inner wall of the lower section downwardly and over said supporting bars o and thence to the rear wall of the ice bunker, is a Wire netting p which serves to prevent small particles of ice and salt from passing through. Passing over said Ic o netting at points directly over said bars o are supplemental bars q, upon which the cakes of ice are-designedV to rest instead-:cf resting: The Vnetting al-Y protect thewire from injury by the cakes ofv ice. The walls of the ice bunker are lined with a partition s forming an air space t be'-` tween the partition s and the interior wall g 1o of the case. This partition has a series of-inclned ports'u leading from the ice bunker into said air space. Said air space t leads downwardly and opens into thelower extremf ity of the ice bunker,and thence through the netting into the drip pan.

The drip pan is formed by the two sides and rear wall of the case, and a partition v between the drip pan'andthe refrigerating room. A considerable portion of the floor of 2o the drip'pan is formed by an inclined/bottom w, extending from the rear wall downwardly and terminating justy before' the-t1ap;' The trap consists of a pipe a: leading Vfrom thedrip pan out of Athe refrigerator case;-l Over the head of the pipe is a strainer head-y near the bottom of which are perforationsz, through 1 which the surplus water escapes.

The top of the refrigerating room'inclines:

downwardly from the partitiony between VKthe 3o ice bunker andsaid Fig. l.

The operation Vof my improved combined refrigerator and freezer is as follows: `Theice is placed in the bunker vthrough. theldoor b. 5 The ineness'of the ice and the quantity2 of salt will depend upon the degree of coid4 it is desired to at tain. The finer the-ice is crushedf and the greater the proportionv of salt,4 the more rapid will be the melting and the colder 4o the temperature. The cold air` in the-ce bunker passes down through the netting directly and also outv through the portsfu and thence through the netting at ythe bottom of the bunker, and thence under-the bunker andl into the bottom of the refrigerating room. 'As" the cold air descends in the bunker,veach space j becomes as it were a siphondrawing the air in the'refrigerating room through said spaces into the ice bunker, and down 5o downward o'f the parts of the sections gives-a downward motion to thecolumn of air-passing through thespaces, and tlieapex of each ,lse'ing'hi/gher than the lower extremity of theA one next above, there will be no drawingof More-- the air horizontally across the bunker. over,this arrangement preventsV `an-y water escaping-from the melting ,ice through' said spaces into the refrigerating room: When 6o refrigerating onlyis required, allthe sections may be complete, as it-will not be necessary to break theice after it is placed in the bunker,

but when it is desired'to reduce the temperature below freezing andA to keep `it at that 6 5- point for a considerable time, it becomes neef essary once in about twenty-four hours to` break the ice in the bottom of the bunker, be-

chamber,- as-'seen Yatt-athrough the ice and netting. The incliningA cause-the air -at that point gradually freezes it againlinto. a solid mass at the bottom of the bunker, and the melting becomes in conse- 7o quence thereof too slow to induce the required temperature. To facilitate the rebreaking of the-ice in the bottom of the bunker, I leave out the half of the partition sections next to the-refrigerating room, as seen in Fig. 1, so that an ice breaking tool can be inserted between said sections into the bottom of the ice bunker. 1

The inclination of the bottom of the drip pan downward andforwsrd toward the re- 8o frigerating room tends to throw the cold air descending from the bunkekabove into the refrigerating room. Again the\ clination of the ceiling of 'the refrigeratingnmm tends to throw the-warmer and drier air-into the 85 bunkerto take the place ofthe colder and moisterairwhichv has passed downward to-r ward thebottom of the bunker. Thus a con tinual circulation of air is obtained passing fro.m--tl1e yrefri'gerating-room Athrough the 9o spaces in the partitioninto the bunker, and thence throughthevbottom'of the Ybunker and back into the refrigerating room, coldanddry.`/
